Yeah, I can't wait until hackers get into car OSs and make the engines quit, shift into reverse on the freeway, floor the accelerator in the driveway, maybe even self-start and drive away under a hacker's control. What a neat concept - steal a car from the comfort of your own home, and have it drive itself to your place, or to your favorite chop shop.
Too late: Remote unlock and start for cars hacked
Of course, this requires a car that can be unlocked using a smartphone app to begin with, so your key-fob unlockable car is probably safe...
I'd love to see cars offer the ability to download your data so you can analyze it yourself (or send it to 3rd parties who can analyze it).
You can now, actually. There are companies that sell devices that plug into the OBD-2 interface (that jack under the dash the dealership uses when you take your car in for service) Yeah, you need to have a bluetooth capable laptop in the car with you to actually capture the data for analyzing, but it's a start...OBDLink
